West Allegheny High School, 205 West Allegheny Road, Imperial Pa 15126. The construction of the current High School building began in 1961 and opened to students in 1962. The academic sections of the building are two stories in height with common areas on the ground level. Renovations in 1972 added a classroom wing, a swimming pool and increased the cafeteria/kitchen areas. In 1992 more classrooms were added along with extensive renovations to the facility, and in 1999 a new 2,000-seat, two-story gymnasium, a music classroom, an expansion to the cafeteria, and an academic classroom wing (including a video studio) were added. As part of that project, the library was moved to the old gym area, a new chorus room was created, and the old library space was converted into classrooms. The kitchen was remodeled incorporating a food-court design in 2006. In 2007 artificial turf was installed in the stadium in addition to other improvements to the stadium grounds. A $26 million two-year project began in 2008 to add a two-story, 22-classroom wing and a two-story locker room/offices/two-classroom addition to the gym. This project also provided for the expansion of the auditorium. An increase in capacity just shy of 1,000 seats was realized by utilizing a new balcony and mezzanine seating area. The project also included relocation and expansion of the tennis court area on the campus and extensive renovations to the rest of the building and its mechanical systems. In addition to the stadium, which has a capacity of approximately 4,000 and includes a press box, scoreboard and concession stand, the campus also includes a softball field, a multipurpose field, a football practice field, four tennis courts and an outdoor classroom. There is on-site parking for approximately 500 cars, including a lot with approximately 200 spaces for student parking. This latest renovation project was completed in 2010 and will allow the district to accommodate the expected increase in enrollment over the next ten years.
